Abstract

Seven-year-old trees of &#39;Lane Late&#39; grafted on three new citrus rootstocks: &#39;Forner-Alcaide n degrees 5&#39; (&#39;FA5&#39;), &#39;Forner Alcaide n degrees 13&#39; (&#39;FA13&#39;) and &#39;Forner-Alcaide n degrees 41&#39; (&#39;FA41&#39;) (hybrids of &#39;Cleopatra&#39; mandarin x Poncirus trifoliata), and three traditional rootstocks: &#39;Carrizo&#39; citrange (Citrus sinensis x Poncirus trifoliata), &#39;Alemow&#39; (Citrus macrophylla) and &#39;Cleopatra&#39; mandarin (Citrus reshni), cultivated in Andalusia (Spain), were evaluated in the season 2010-2011. They were characterized as their effects on fruit appearance, taste and nutritional compounds. &#39;FA5&#39; and &#39;Cleopatra&#39; madarin maintained fruit quality on the tree for longer time, indicating that they are the most suitable for late harvested cultivars such as &#39;Lane Late&#39;. &#39;Alemow&#39; and &#39;Carrizo&#39; citrange showed a faster loss of organoleptic quality due to their lower acidity of the juice. &#39;Alemow&#39; produced larger fruits than &#39;Cleopatra&#39; mandarin and &#39;FA13&#39;, although it also produced the lowest juice content and the poorest organoleptic quality. In relation to the remaining quality parameters, &#39;Alemow&#39; and &#39;Carrizo&#39; citrange had the lowest values in fruit firmness, total polyphenols content and antioxidant activity. &#39;Cleopatra&#39; mandarin, &#39;FA13&#39; and &#39;FA5&#39; had the highest antioxidant activity, while &#39;FA13&#39; showed the highest fruit firmness, similar to &#39;FA41&#39; and &#39;FA5&#39;.
